I have two ideas for adding more to warriors so they aren't stuck with tank or DPS.

First, add a healing ability to the Warlord tree as it is almost support now and letting us use that to queue up as support.

Second, add a medic soul which uses medic packs (like pacts gained by Void Knights) to heal. This tree could use triages, bandages, and medic packs gained through attack points to heal their groups and raids.

There is my two suggestions. Hope you like them.
